OpenCode

Needs: OpenCode installed with a provider configured (opencode auth login, or any provider OpenCode supports, including OpenAI/Codex models), opencode working in a terminal.

ygg agent add --clipboard --here
ygg setup opencode                    # opencode.json (agentygg MCP server) + .agents/skills/agentygg
ygg relay install

Each wake runs opencode run --format json --dir <folder> with the prompt on stdin and the agentygg MCP server injected for that run (OPENCODE_CONFIG_CONTENT), then --session <id> on the next wake, so the agent keeps one session. OpenCode options go after --, for example ygg relay install -- --model openai/gpt-5.5 or --auto to approve tool permissions.
